Quoting ptrjong (Thread starter):Am I seeing things, of might this make any sense? If so, what might cause it? And what might fix it?

Could you perhaps post some examples? It sounds like you're describing chromatic aberration which is caused by flaws in the lens, but is often correctable with software. It would be best to see some examples to be sure.

Quoting ptrjong (Reply 3):There is a way of removing some red or adding some blue to the highlights, though. I think I'm starting to learn how to deal with this, but would rather prevent it in the first place.

That sounds like chromatic aberration from the lens. I personally use LR 4.2 and it removes this kind of aberration very well. Just use either the lens profile and/or tick the Remove Chromatic Aberration box. Sometimes atmosphere can cause this kind of effect too.

The light parties seem a bit too red, and the dark parties a bit too blue. To be honest I don't see it myself, but the pixel info confirms it to some extent, and this often seems to be noticeable for you screeners, at least after my editing.

If you tell me this picture is fine colour-wise, then I'm obviously over-editing at some point.

No, I definitely notice the pink cast you're talking about. The atmospheric conditions (i.e. very low contrast) may be exacerbating it. Can't say for sure what's causing it, but possibly camera related. If you have the raw file, that would be pretty useful in determining whether it's that or maybe something else. You can send me it if you do.

I see the same thing quite frequently with my 50D. When editing the RAW file prior to exporting, I've gotten in the habit of tweaking the red channel a bit to reduce the cast. If it needs more, then when editing the JPEG, I'll either use color balance, or more commonly, I'll go to Levels, select the red channel, and move the midtones slider down to somewhere between .92 and .97, depending on how much correction is needed.

Someone else on here mentioned that technique, but I can't remember who.

The worst is shooting against an overcast sky. Those are a giant pain to color balance properly when everything seems to have a red cast.

So, having seen the RAW file, it does seem that it is a very simple white-balance issue, which is of course easily fixed when converting from RAW (somewhat relevant to the other thread about shooting jpeg vs. RAW, as this kind of correction is typically much more difficult when working from a jpeg only). Vik, the in-camera white balance settings applied do have that slightly red cast you describe, but he's using a Nikon.
